Based on the size of the maintenance worker compound by the side of the M4 motorway and the number of vehicles there during the day I'm a bit surprised that by now you aren't doing work on three bridges simultaneously every weekend to finish this work much earlier. Why only one bridge at a time ? Seems obvious to me whilst things are quiet it makes perfect sense.
